annulus of 3 to 5 rows of small cells; lid short rostrate, nearly half length 

 of capsule; peristome short, teeth red, on a very short orange basal mem- 

 brane, scarcely twisted. Braithw. Brit. Moss Flora 1; 266. On earth by a 

 brook: Lytton, B. C. 



140. Barbula pseudo-rigidula Kindb. Agrees with B. rigidula in 

 tufts fuscescent: leaves from a short erect base, patent or recurved, con- 

 torted when dry, long lanceolate, revolute below, nearly smooth; basal 

 cells pellucid and rectangular; costa brown, nearly filling narrow acumen: 

 differs in leaf borders not thickened, inner perichsetial leaves from an 

 oblong base, narrow acuminate with a long excurrent costa: peristome 

 pale and distinctly contorted. Mac. Cat. 264. On earth by a brook: 

 Lytton, B. C. 



141. Barbula circinnatula C. M. & Kindb. Nearly allied to B. cylin- 

 drica or rather intermediate between B. elata and B. virescens: differs 

 in upper leaves green, circinnate-twisted when dry: peristome paler and 

 annulus simple: leaf cells more distinct. Mac. Cat. 56. On earth on 

 rocks: Agassiz, B. C. 



142. Barbula horridifolia C. M. & Kindb. Densely tufted: plants 

 about 3 cm. high, green above, rusty red below, more or less branching: 

 leaves crispate when dry, when moist falcate, spreading at all sides, very 

 long and narrow, ovate-lanceolate, carinate above, loosely disposed and 

 long-decurrent, nearly smooth; borders reflexed at ovate base, basal cells 

 pellucid, short rectangular, inner larger, upper cells small and obscure; 

 costa red-brown, broader below, narrow above, vanishing in apex: barren. 

 Mac. Cat. 57. On damp rocks: Columbia River, B. C. 



143. Barbula robustifolia C. M. & Kindb. Very nearly allied to B. 

 tortellifolia: differs in dark brown or olive-green color of whole plant: 

 leaves more crowded, shorter, with an ovate oblong base, borders reflexed 

 nearly to the middle on one side; upper cells larger and subpellucid, basal 

 ones hyaline, and subquadrate; costa thicker and not excurrent, linear and 

 distinct to apex: barren. Mac. Cat. 56. Abundant on rocks: Vancouver; 

 British Columbia. 



144. Barbula tortellifolia C. M. & Kindb. Very much resembling B. 

 horridifolia in habit: generally more robust (often 4-5 cm.) and finally 

 sometimes quite red: stem more divided: leaves broader, less distinctly 

 decurrent, comal ones larger and crowded, short-pointed by excurrent 

 costa: perichsetial leaves suddenly acuminate, costa faintly excurrent 

 capsule large, subcylindric, reddish, twice longer than beak; peristome 

 long, once loosely contorted, whitish: dioicous. Mac. Cat. 56. On wet 

 rocks: Vancouver and B. C. 



145. Barbula subcylindrica Broth. Dioicous: tufts densely cespitose, 

 pulvinate, dark colored above: stems up to 6 cm. high, erect, flexuous, 

 dichotomously branched, branches fastigiate, densely foliate: leaves when
